Summary of the Invention

Problems to be Solved by the Invention

[0004] In recording devices capable of recording on a roll body in which recording media are wound in a roll shape, such as the image forming apparatus described in Patent Document 1, the conveyed recording media may be conveyed at an angle. Therefore, the image forming apparatus described in Patent Document 1 discloses detecting the position of the edge of the paper during conveyance, detecting skewed conveyance from the displacement of this position, and adjusting the back tension according to the amount of skew. However, skewed conveyance of the recording media is often due to the way the roll body is set, and Patent Document 1 does not describe a method of setting the roll body to suppress skewed conveyance during setting, so-called skew correction during roll body setting. Furthermore, in conventional recording devices that can set the roll body on one side in the front-to-back direction of the recording device, record on the recording media of the roll body, and discharge from the other side in the front-to-back direction, the user is often forced to move back and forth between the front and back of the recording device many times when setting the roll body, there is a risk of damage to the recording media, and the accuracy of skew correction is almost always low. Therefore, there is a need for a method of skew correction that is easy, does not damage the recording media, and has high accuracy. [Means for solving the problem]

[0005] The recording device of the present invention, which solves the above problems, comprises: a holding part for holding a roll body in which recording media are wound in a roll shape; a rotating mechanism for rotating the holding part to rotate the roll body; a pair of transport rollers for transporting the recording media by nipping and rotating them; a recording part for recording on the recording media transported by the pair of transport rollers; a first detection part positioned downstream of the recording part in the transport direction of the recording media and detecting the leading edge of the recording media in the transport direction; a notification part for notifying information; and a control unit for controlling the rotating mechanism, the pair of transport rollers, the recording part, the first detection part, and the notification part, wherein the control unit, with the nip of the pair of transport rollers open, monitors by a first monitoring operation whether the leading edge inserted between the pair of transport rollers from the holding part side in the transport direction has been detected by the first detection part, and, upon detection of the leading edge by the first detection part, executes a first notification operation to notify the notification part that the leading edge has been detected by the first detection part.

[0006] Furthermore, the present invention provides a control method for a recording device to solve the above problems, comprising: a holding unit for holding a roll body in which recording media are wound in a roll shape; a rotating mechanism for rotating the holding unit to rotate the roll body; a pair of transport rollers for transporting the recording media by nipping and rotating them; a recording unit for recording on the recording media transported by the pair of transport rollers; a first detection unit positioned downstream of the recording unit in the transport direction of the recording media and detecting the leading edge of the recording media in the transport direction; and a notification unit for notifying information, wherein, with the nip of the pair of transport rollers open, a first monitoring operation is performed to check whether the leading edge inserted between the pair of transport rollers from the holding unit side in the transport direction has been detected by the first detection unit, and a first notification operation is performed to notify the notification unit that the leading edge has been detected by the first detection unit.

[Figure 7] A flowchart illustrating an example of a control method for the recording device in Reference Example 3. [Modes for carrying out the invention]

[0008] First, the present invention will be described in general terms. A recording device according to a first aspect of the present invention for solving the above problems comprises: a holding unit for holding a roll body in which recording media are wound in a roll shape; a rotating mechanism for rotating the holding unit to rotate the roll body; a pair of transport rollers for transporting the recording media by nipping and rotating them; a recording unit for recording on the recording media transported by the pair of transport rollers; a first detection unit positioned downstream of the recording unit in the transport direction of the recording media and detecting the leading edge of the recording media in the transport direction; a notification unit for notifying information; and a control unit for controlling the rotating mechanism, the pair of transport rollers, the recording unit, the first detection unit, and the notification unit, wherein the control unit, with the nip of the pair of transport rollers open, monitors by a first monitoring operation whether the leading edge inserted between the pair of transport rollers from the holding unit side in the transport direction has been detected by the first detection unit, and, upon detection of the leading edge by the first detection unit, executes a first notification operation to notify the notification unit that the leading edge has been detected by the first detection unit.

[0009] According to this embodiment, a first detection unit is provided for detecting the leading edge of the recording medium in the transport direction. With the nip of the transport roller pair open, a first monitoring operation monitors whether the leading edge has been detected by the first detection unit. When the leading edge is detected by the first detection unit, the notification unit notifies that the leading edge has been detected by the first detection unit. For example, a user can feed out the recording medium from the set position side of the roll body with the nip of the transport roller pair open, and the notification from the notification unit will stop the feeding of the recording medium at the precise position where the leading edge has reached the first detection unit, allowing the user to nip the recording medium with the transport roller pair while remaining on the set position side of the roll body. If the feed length of the recording medium is too long, the recording medium may be damaged by contact with the mounting surface of the recording device. Also, if the feed length of the recording medium is too short, the skew accuracy may decrease. This is because skew adjustment during roll body setting is performed by rewinding the fed-out recording medium and wrapping it around the roll body, but if the rewinding distance is too short, the skew adjustment may be insufficient. Furthermore, repeatedly transporting and retracing a recording medium while it is nipped by the transport roller pair can damage the recording medium. Therefore, by allowing the user to remain on the set position side of the roll body and release the nip while feeding out the recording medium by the appropriate length to perform skew correction, skew correction can be performed easily and with high precision without damaging the recording medium.

[0010] A recording device according to a second aspect of the present invention, in the first aspect, comprises an operation unit for receiving operation input, and the control unit controls the rotation mechanism to wrap the recording medium around the roll body in response to receiving an input from the operation unit for a reverse transport operation to transport the recording medium in the opposite direction to the transport direction after the execution of the first notification operation.

[0011] According to this embodiment, after the execution of the first notification operation, the recording medium is wrapped around the roll body in response to the acceptance of a reverse transport operation input from the operation unit. Therefore, skew can be corrected in response to the acceptance of a reverse transport operation input from the user.

[0012] A recording device according to a third aspect of the present invention, in the second aspect, is provided with a second detection unit for detecting the tip between the recording unit and the first detection unit, the control unit monitors whether the tip has been detected by the second detection unit through a second monitoring operation, and terminates the reverse transport and winding of the recording medium onto the roll body upon detection of the tip by the second detection unit.

[0013] According to this embodiment, a second detection unit is provided between the recording unit and the first detection unit, and when the leading edge of the recording medium is detected by the second detection unit, reverse transport and winding of the recording medium onto the roll are terminated. As a result, the skewed recording medium can be positioned in an appropriate location, and for example, recording can be started immediately from a desired position on the recording medium.

[0014] A recording device according to a fourth aspect of the present invention is characterized in that, in the third aspect, the control unit performs a second notification operation to cause the notification unit to notify the second detection unit that the tip has been detected by the second detection unit in the second monitoring operation.

[0015] According to this embodiment, when the tip is detected by the second detection unit during the second monitoring operation, the notification unit is notified that the tip has been detected by the second detection unit. As a result, the user can quickly recognize that the recording medium has been placed in the correct position.

[0016] A recording device according to a fifth aspect of the present invention is characterized in that, in the fourth aspect, the control unit performs a third notification operation after the execution of the second notification operation, instructing the notification unit to nip the recording medium with the transport roller pair and to prompt the start of recording.

[0017] According to this embodiment, after the execution of the second notification operation, the notification unit is instructed to nip the recording medium with the transport roller pair and to prompt the user to start recording. Therefore, the user can start recording quickly.

[0018] In the recording apparatus according to the sixth aspect of the present invention, in any one of the second to fifth aspects, when starting recording after reverse conveyance of the recording medium, if the recording medium is not nipped by the pair of conveyance rollers, the control unit controls the operation unit so as not to accept an input of an operation instruction to start recording from the operation unit until the recording medium is nipped by the pair of conveyance rollers.

[0019] According to this aspect, when starting recording after reverse conveyance of the recording medium, if the recording medium is not nipped by the pair of conveyance rollers, an input of an operation instruction to start recording from the operation unit is not accepted until the recording medium is nipped by the pair of conveyance rollers. For this reason, it is possible to suppress recording from being started in a state where the recording medium is not nipped and the recording medium is not properly conveyed.

[0020] In the recording apparatus according to the seventh aspect of the present invention, in the sixth aspect, when starting recording after reverse conveyance of the recording medium, if the recording medium is not nipped by the pair of conveyance rollers, the control unit executes a fourth notification operation for causing the notification unit to notify that the pair of conveyance rollers nip the recording medium.

[0021] According to this aspect, when starting recording after reverse conveyance of the recording medium, if the recording medium is not nipped by the pair of conveyance rollers, the notification unit is caused to notify that the pair of conveyance rollers nip the recording medium. For this reason, the user can quickly recognize that the recording medium is not nipped by the pair of conveyance rollers and recording cannot be started.

[0022] In the recording apparatus according to the eighth aspect of the present invention, in any one of the first to seventh aspects, a plurality of the first detection units are provided in the conveyance direction, and the control unit determines which of the plurality of first detection units to use according to the type of the recording medium.

[0023] According to this embodiment, a plurality of first detection units are provided in the transport direction. Therefore, the control unit can adopt the detection result of the first detection unit at an appropriate position depending on the ease of skew correction, for example, due to the type and width of the recording medium, and can perform skew correction with particularly high accuracy.

[0024] A recording device according to the ninth aspect of the present invention, in any one of the first to eighth aspects, is characterized in that it includes a heating unit for heating the recording medium being transported, located downstream of the recording unit in the transport direction, and the first detection unit is located at a position different from the heating region of the recording medium by the heating unit in the transport direction.

[0025] According to this embodiment, the device includes a heating unit that heats the recording medium transported downstream of the recording unit in the transport direction, and the first detection unit is located at a position different from the heating region of the recording medium by the heating unit in the transport direction. Therefore, damage to the first detection unit due to heating by the heating unit can be suppressed.

[0026] A control method for a recording device according to a tenth aspect of the present invention is a control method for a recording device comprising: a holding unit for holding a roll body in which recording media are wound in a roll shape; a rotating mechanism for rotating the holding unit to rotate the roll body; a pair of transport rollers for transporting the recording media by nipping and rotating them; a recording unit for recording on the recording media being transported by the pair of transport rollers; a first detection unit positioned downstream of the recording unit in the transport direction of the recording media and detecting the leading edge of the recording media in the transport direction; and a notification unit for notifying information, characterized in that, with the nip of the pair of transport rollers released, a first monitoring operation is performed to monitor whether the leading edge inserted between the pair of transport rollers from the holding unit side in the transport direction has been detected by the first detection unit, and if the leading edge has been detected by the first detection unit, a first notification operation is performed to notify the notification unit that the leading edge has been detected by the first detection unit.

[0027] According to this embodiment, a first detection unit is provided for detecting the leading edge of the recording medium in the transport direction. With the nip of the transport roller pair open, a first monitoring operation monitors whether the leading edge has been detected by the first detection unit. When the leading edge is detected by the first detection unit, the notification unit notifies that the leading edge has been detected by the first detection unit. Therefore, the user can remain on the set position side of the roll body and perform skew correction by feeding out the recording medium by the appropriate length with the nip open, enabling easy and highly accurate skew correction without damaging the recording medium.

[0028] [Example 1] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. First, an overview of the recording device 1 according to Embodiment 1 of the present invention will be described with reference to Figure 1. Note that in Figure 1, some components are omitted to make the configuration easier to understand. Here, the X-axis direction in the figure is the horizontal direction and is the direction in which the rotation axis of the holding part 3 that holds the roll body R1 in which the recording medium M is wound into a roll extends, the Y-axis direction is the horizontal direction and is the front-to-back direction of the recording device 1 and is perpendicular to the X-axis direction, and the Z-axis direction is the vertical direction. Furthermore, in the following, the direction of the arrow will be considered the + direction, and the direction opposite to the direction of the arrow will be considered the - direction. For example, the vertically upward direction is the +Z direction, the vertically downward direction is the -Z direction, the front of the recording device 1 is the +Y direction, and the rear of the recording device 1 is the -Y direction.

[0029] The recording device 1 of this embodiment includes a main body 2, and a holding part 3 is provided on the rear side of the main body 2 in the -Y direction to hold a roll body R1 in which the recording medium M is wound in a roll shape. In the recording device 1 of this embodiment, when the recording medium M is transported in the transport direction A, the holding part 3, which has a rotation axis along the X axis direction, rotates in the rotation direction C. In this embodiment, a roll body R1 is used in which the recording surface to be recorded is wound outwards, but if a roll body R1 is used in which the recording surface is wound inwards, the holding part 3 can rotate in the opposite direction to the rotation direction C to feed out the recording medium M from the roll body R1.

[0030] Furthermore, the recording device 1 of this embodiment includes a transport path for the recording medium M, consisting of a media support section 4, a media support section 10, and a media support section 11, etc. The recording device 1 also includes a transport roller pair 7, consisting of a drive roller 5 and a driven roller 6, for transporting the recording medium M in the transport direction A along the transport path. In this embodiment, the drive roller 5 is composed of a roller that extends in the width direction B intersecting the transport direction A, and the driven rollers 6 are arranged in a row in the width direction B relative to the drive roller 5 at a position opposite the drive roller 5. However, there are no particular limitations on the configuration of the transport roller pair 7 as long as it is possible to transport the recording medium M by nipping it.

[0031] Furthermore, the recording device 1 of this embodiment includes a head 8, which serves as a recording unit and has multiple nozzles positioned opposite the media support unit 10, from which ink is ejected for recording, and a carriage 9 on which the head 8 is mounted and which is capable of reciprocating in the width direction B. In the recording device 1 of this embodiment, the transport direction A at the position opposite the head 8 on the media support unit 10 is the +Y direction, the width direction B, which is the direction of movement of the head 8, is along the X-axis direction, and the ink ejection direction is the -Z direction.

[0032] With the above configuration, the head 8 can record by ejecting ink from nozzles (not shown) onto the transported recording medium M while reciprocating in the width direction B intersecting the transport direction A. The recording device 1 of this embodiment can form a desired image on the recording medium M by repeatedly transporting the recording medium M in the transport direction A at a predetermined transport amount, and then moving the head 8 in the width direction B while ejecting ink with the recording medium M stopped. However, instead of a head with such a configuration, a so-called line head may be provided in which nozzles for ejecting ink are provided along the entire X-axis direction.

[0033] Furthermore, a heating unit 14 is provided at a position opposite the media support unit 11. In this embodiment, the heating unit 14 is an infrared heater 14A that irradiates infrared rays into the heating range R1 of the media support unit 11. However, there are no particular limitations on the configuration of the heating unit 14.

[0034] A first detection unit 12 (first detection unit 12A) capable of detecting the leading edge of the recording medium M in the transport direction A is provided downstream of the heating range R1 of the media support unit 11 in the transport direction A. A second detection unit 13 capable of detecting the leading edge of the recording medium M in the transport direction A is provided upstream of the heating range R1 of the media support unit 11 in the transport direction A. Here, the media support unit 11 is provided with a groove 11A between the heating range R1 and the second detection unit 13 to prevent heat from the heating unit 14 from being transmitted to the second detection unit 13, and similarly, a groove 11B is provided between the heating range R1 and the first detection unit 12 to prevent heat from the heating unit 14 from being transmitted to the first detection unit 12.

[0035] Furthermore, a guide bar 15 is provided downstream of the media support section 11 in the transport direction A, with a contact portion with the recording medium M extending in the width direction B, enabling the recording medium M to be subjected to desired tension. However, a configuration without the guide bar 15 is also possible. Note that the recording device 1 in this embodiment is configured as shown in Figure 1, but is not limited to this configuration.

[0036] Furthermore, downstream of the guide bar 15 in the transport direction A, a winding shaft 16 is provided that winds the recording medium M being transported in the transport direction A into a roll body R2. In this embodiment of the recording device 1, the holding unit 3 and the winding shaft 16 have the same configuration and are configured to support the paper tube, which is the rotation center of the roll bodies R1 and R2, and to rotate the paper tube in the rotation direction C.

[0037] Next, the electrical configuration of the recording device 1 in this embodiment will be described. Figure 2 is a block diagram showing the electrical configuration of the recording device 1 in this embodiment. The control unit 31 is equipped with a CPU 32 that controls the entire recording device 1. The CPU 32 is connected to the storage unit 34 via a system bus 33. The storage unit 34 includes a ROM that stores various control programs executed by the CPU 32, a RAM that can temporarily store data, and an EEPROM, which is a non-volatile memory that can store data after rewriting.

[0038] Here, the CPU 32 is connected via the system bus 33 to a first detection unit 12 that detects the leading edge of the recording medium M in the transport direction A. The CPU 32 is also connected via the system bus 33 to a second detection unit 13 that detects the leading edge of the recording medium M in the transport direction A. Furthermore, the CPU 32 is connected via the system bus 33 to a head drive unit 37 for driving the head 8.

[0039] Furthermore, the CPU 32 is connected to a motor drive unit 38 via a system bus 33, which is connected to the carriage motor 39, transport motor 40, delivery motor 41, and winding motor 42. Here, the carriage motor 39 is a motor for moving the carriage 9, on which the head 8 is mounted, in the width direction B. The transport motor 40 is a motor for driving the drive rollers 5 that constitute the transport roller pair 7. The delivery motor 41 is the rotation mechanism of the holding unit 3 and is a motor that drives the holding unit 3 to deliver the recording medium M to the transport roller pair 7. The winding motor 22 is a drive motor for rotating the winding shaft 16.

[0040] Furthermore, the CPU 32 is connected via the system bus 33 to a heating unit drive unit 35 that drives the heating unit 14. In addition, the CPU 32 is connected via the system bus 33 to an input / output unit 43. The input / output unit 43 is connected to an operation panel 44 having a monitor that can notify the user of information and buttons that accept user input, as well as a PC 45 for transmitting and receiving data such as recorded data and signals.

[0041] In this embodiment, the control unit 31 is configured to control the head 8, drive roller 5, carriage 9, heating unit 14, and the like. By controlling the head 8, drive roller 5, carriage 9, heating unit 14, and the like, the recording device 1 of this embodiment can perform a recording operation. Specifically, the recording medium M is fed out from the holding unit 3 and wound up by the winding shaft 16, while the recording medium M is transported by the transport roller pair 7 by a predetermined amount. At the same time, the head 8 is moved in the width direction B, ink is ejected from the head 8, and the ink ejected from the head 8 onto the recording medium M is heated and dried by the heating unit 14 while performing the recording operation.

[0042] Next, with reference to the flowchart in Figure 3, we will describe an embodiment of a control method for the recording device that can be implemented using the recording device 1 described above, and in detail, a method for setting the roll body R1 into the recording device 1 until it is ready to start recording. Before describing the control method of the recording device in this embodiment, we will describe the control method of a reference example recording device with reference to Figures 5 to 7.

[0043] First, the control method for the recording device of Reference Example 1, shown in the flowchart of Figure 5, will be explained. In the control method for the recording device of Reference Example 1, first, in step S110, the roll body R1 is held in the holding unit 3. Next, in step S120, the recording medium M is fed out from the roll body R1 along the transport direction A by the user with the nip of the transport roller pair 7 released by the user's manual operation. Next, in step S210, when the leading edge of the recording medium M in the transport direction A passes the nip position of the transport roller pair 7, the transport roller pair 7 nip the recording medium M. Up to this point, the user performs the work behind the recording device 1.

[0044] Then, in step S220, the user moves to the front of the recording device 1. Then, in step S230, the user releases the nip of the transport roller pair 7 while holding the recording medium M. Next, in step S240, the recording medium M is pulled forward, and when the user determines that the recording medium M has been pulled forward by a predetermined amount, in step S250 the recording medium M is nipped by the transport roller pair 7.

[0045] Subsequently, in step S260, the user moves to the rear of the recording device 1. Then, in step S270, the user winds up the recording medium M by releasing the nip of the transport roller pair 7 and winding a predetermined amount of the recording medium M onto the roll body R1. When the user determines that the predetermined amount of recording medium M has been wound up, in step S280, the transport roller pair 7 nip the recording medium M, and the control method of the recording device of Reference Example 1, shown in the flowchart of Figure 5, is terminated. Thus, in the control method of the recording device of Reference Example 1, shown in the flowchart of Figure 5, the user repeatedly moves back and forth from the front of the recording device 1. In other words, the control method of the recording device of Reference Example 1, shown in the flowchart of Figure 5, is a cumbersome and burdensome operation for the user.

[0046] Next, the control method for the recording device of Reference Example 2, shown in the flowchart of Figure 6, will be explained. In the control method for the recording device of Reference Example 2, steps S110, S120, and S210 are the same as in the control method for the recording device of Reference Example 1. After step S210 is executed, automatic skew correction is performed in step S310. Automatic skew correction involves repeatedly transporting the recording medium M with the transport roller pair 7, feeding it out in the transport and holding unit 3, and then transporting the recording medium M in the reverse direction and winding it up in the holding unit 3. Note that "reverse transport" means moving the recording medium M in the opposite direction to the transport direction A.

[0047] As described above, automatic skew correction is performed with the recording medium M nipped by the transport roller pair 7. If the recording medium M is repeatedly transported and then reversed while nipped by the transport roller pair 7, there is a risk that the recording medium M may be damaged due to the nipping pressure of the transport roller pair 7.

[0048] Next, the control method for the recording device of Reference Example 3, represented by the flowchart in Figure 7, will be explained. In the control method for the recording device of Reference Example 3, steps S110 and S120 are the same as in the control methods for the recording devices of Reference Examples 1 and 2. After step S120 is executed, the recording medium M is wound onto the roll body R1 in step S410, and the recording medium is nipped in step S420. Step S410 is the same as step S270 in the control method for the recording device of Reference Example 1, and step S420 is the same as step S280 in the control method for the recording device of Reference Example 1.

[0049] Here, the amount of recording medium M sent out after step S120 and before starting step S410 is an amount of the user's choosing. Since the user sends out the recording medium M from the back to the front of the recording device 1, it is difficult to grasp the amount sent out. If the amount of recording medium M sent out is too much, the recording medium M may come into contact with the mounting surface of the recording device 1 at the front of the recording device 1 and be damaged. On the other hand, if the amount of recording medium M sent out is too little, the amount of recording medium M being transported back to the roll body R1 in step S410 may be too small, resulting in low accuracy in skew correction.

[0050] As described above, the control methods for the recording devices in the reference examples shown in the flowcharts from Figures 5 to 7 all made it difficult to perform skew correction with high precision without damaging the recording medium M. Therefore, the control method for the recording device of this embodiment, shown in the flowchart of Figure 3, will now be explained.

[0051] In the control method of the recording device of this embodiment, steps S110 and S120 are the same as the control methods of the recording devices of Reference Examples 1 to 3. After step S120 is performed, in step S130, the control unit 31 determines whether or not the leading edge of the medium M in the transport direction A has been detected by the first detection unit 12. That is, step S130 is repeated until the leading edge of the medium M in the transport direction A is detected by the first detection unit 12, and once the leading edge of the medium M in the transport direction A is detected by the first detection unit 12, the process proceeds to step S140.

[0052] In step S140, the control unit 31 controls a buzzer (not shown) to sound and displays on the monitor on the operation panel 44 that the leading edge of the medium M in the transport direction A has been detected by the first detection unit 12. In this embodiment, the medium detection information is notified by sounding a buzzer and displaying on the monitor on the operation panel 44 that the leading edge of the medium M in the transport direction A has been detected by the first detection unit 12. However, the notification method is not limited to this, and for example, it may be sufficient to simply sound a buzzer or to simply illuminate a light (not shown).

[0053] Next, in step S150, the recording medium M is nipped by the transport roller pair 7. Then, in step S160, the control unit 31 controls the recording medium M to be transported in the reverse direction until the second detection unit 13 detects the leading edge of the medium M in the transport direction A, thus ending the control method of the recording device in this embodiment.

[0054] As described above, the control method for the recording device of this embodiment is a control method for a recording device comprising: a holding unit 3 that holds a roll body in which the recording medium M is wound in a roll shape; a delivery motor 41 which is a rotation mechanism that rotates the roll body R1 by rotating the holding unit 3; a transport roller pair 7 that transports the recording medium M by nipping and rotating it; a head 8 that performs recording on the recording medium M transported by the transport roller pair 7; a first detection unit 12 which is positioned downstream of the head 8 in the transport direction A and detects the leading edge of the recording medium M in the transport direction A; and an operation panel 44 which is an announcement unit that announces information. When the nip of the transport roller pair 7 is released, the first monitoring operation in step S130 monitors whether or not the leading edge of the recording medium M has been detected by the first detection unit 12, and when the leading edge is detected by the first detection unit 12, the first announcement operation in step S140 is performed to notify the announcement unit that the leading edge of the recording medium M has been detected by the first detection unit 12.

[0055] To explain the above from the perspective of the recording device 1, the recording device 1 of this embodiment includes a control unit 31 that controls a delivery motor 41, a transport roller pair 7, a head 8, a first detection unit 12, and an operation panel 44. The control unit 31 monitors whether the leading edge of the recording medium M has been detected by the first detection unit 12 when the nip of the transport roller pair 7 is open, using a first monitoring operation. If the leading edge of the recording medium M has been detected by the first detection unit 12, the control unit 31 performs a first notification operation to notify the operation panel 44 that the leading edge of the recording medium M has been detected by the first detection unit 12.

[0056] The recording device 1 of this embodiment can perform the control method of the recording device described above. For example, the user can release the nip of the transport roller pair 7, feed the recording medium M from the set position side (rear side: -Y direction side) of the roll body R1, and stop the feeding of the recording medium M at the precise position where the leading edge of the recording medium M reaches the first detection unit 12, as notified by the operation panel 44. The recording medium M can then be nipped by the transport roller pair 7 while remaining on the set position side of the roll body R1. If the feed length of the recording medium M is too long, the recording medium M may be damaged by contact with the installation surface of the recording device 1. Also, if the feed length of the recording medium M is too short, the skew accuracy may decrease. This is because skew is corrected when the roll body R1 is set by rewinding the recorded medium M that has been fed out and wrapping it around the roll body R1, but if the rewinding distance is too short, the skew may be insufficient. Furthermore, the recording medium M may be damaged if the transport roller pair 7 repeatedly transports and reverses the recording medium M while it is nipped by the transport roller pair 7. Therefore, by performing the above control method for the recording device, the user can remain on the set position side of the roll body R1 and perform skew correction by feeding out the recording medium M to the appropriate length with the nip released. This allows for easy and highly accurate skew correction without damaging the recording medium M.

[0057] Furthermore, in step S160, the recording device 1 of this embodiment can control the delivery motor 41 to wrap the recording medium M around the roll body in response to receiving an input for a reverse transport operation from the operation panel 44, which can receive user input, to transport the recording medium M in the opposite direction to the transport direction A. Therefore, the recording device 1 of this embodiment can skew in response to receiving an input for a reverse transport operation from the user.

[0058] Furthermore, the recording device 1 of this embodiment includes a second detection unit 13 between the head 8 and the first detection unit 12 for detecting the leading edge of the recording medium M. In step S160, the control unit 31 monitors whether the leading edge of the recording medium M has been detected by the second detection unit 13 through a second monitoring operation. If the leading edge of the recording medium M is detected by the second detection unit 13, the control unit 31 terminates reverse transport and winding of the recording medium M onto the roll body R1. As a result, the recording device 1 of this embodiment can position the skewed recording medium M in an appropriate position, and for example, recording can be started immediately from a desired position on the recording medium M.

[0059] Furthermore, in the second monitoring operation of step S160, the control unit 31 can perform a second notification operation to notify the operation panel 44 or the like that the leading edge of the recording medium M has been detected by the second detection unit 13. Therefore, by using the recording device 1 of this embodiment, the user can quickly recognize that the recording medium M has been placed in the correct position.

[0060] Furthermore, after executing the second notification operation, the control unit 31 can execute a third notification operation, which notifies the operation panel 44 or the like that the transport roller pair 7 should nip the recording medium M and prompts the user to start recording. Therefore, by using the recording device 1 of this embodiment, the user can start recording quickly.

[0061] Furthermore, the recording device 1 of this embodiment has a nip monitoring mechanism that monitors the nip state of the transport roller pair 7. Based on the results of the nip monitoring mechanism, when starting recording after the reverse transport of the recording medium M in step S160, the control unit 31 can control the operation panel 44 so as not to accept input of a recording start operation instruction from the operation panel 44 until the recording medium M is nipped by the transport roller pair 7, if the recording medium M is not nipped by the transport roller pair 7. Therefore, by using the recording device 1 of this embodiment, it is possible to prevent recording from starting when the recording medium M is not nipped and the recording medium M is not transported properly.

[0062] Furthermore, when recording is started after the reverse transport of the recording medium M in step S160, the control unit 31 can prompt the operation panel 44 to nip the recording medium M with the transport roller pair 7 if the recording medium M is not nipped by the transport roller pair 7. Therefore, by using the recording device 1 of this embodiment, the user can quickly recognize that the recording medium M is not nipped by the transport roller pair 7 and that recording cannot be started.

[0063] Furthermore, as described above, the recording device 1 of this embodiment is equipped with a heating unit 14 that heats the recording medium M being transported, downstream of the head 8 in the transport direction A, and the first detection unit 12 is located at a position different from the heating region R1 of the recording medium M by the heating unit 14 in the transport direction A. Therefore, the recording device 1 of this embodiment is configured to prevent the first detection unit 12 from being heated and damaged by the heating unit 14. In this embodiment, not only the first detection unit 12 but also the second detection unit 13 is located at a position different from the heating region R1 of the recording medium M by the heating unit 14. Therefore, the recording device 1 of this embodiment is configured to prevent the second detection unit 13 from being heated and damaged by the heating unit 14.

[0064] [Example 2] The recording device 1 of Example 2 will be described below with reference to Figure 4. Figure 4 corresponds to Figure 1 of the recording device 1 of Example 1. Furthermore, the recording device 1 of this example is the same as the recording device 1 of Example 1 except for the configuration described below, and therefore has the same characteristics as the recording device 1 of Example 1. In Figure 1, components common to both Example 1 and Example 1 are indicated by the same reference numerals, and detailed explanations are omitted.

[0065] As shown in Figure 1, the recording device 1 of Embodiment 1 is equipped with an infrared heater 14A as a heating unit 14, and a first detection unit 12A is provided as a first detection unit 12 at a position different from the heating region R1 of the infrared heater 14A. On the other hand, as shown in Figure 4, the recording device 1 of this embodiment is equipped with a nichrome wire heater 14B as a heating unit 14, and two first detection units 12A and first detection unit 12B are provided as a first detection unit 12 at a position different from the heating region R2 of the nichrome wire heater 14B.

[0066] As described above, the recording device 1 of this embodiment is equipped with multiple first detection units 12 in the transport direction A. The recording device 1 of this embodiment can receive user input such as the type and width of the recording medium M to be used via the operation panel 44. Therefore, the control unit 31 of the recording device 1 of this embodiment can, for example, adopt the detection result of the first detection unit 12 at an appropriate position depending on the ease of skew correction derived from the type and width of the recording medium M to be used. For this reason, the recording device 1 of this embodiment can perform skew correction with particularly high precision.

[0067] The present invention is not limited to the embodiments described above, and can be realized in various configurations without departing from its spirit. For example, an encoder may be provided in the holding unit 3, and the position of the leading edge of the recording medium M may be determined by using the encoder reading result and data such as the roll diameter of the roll body R1 instead of the detection result of the first detection unit 12. Furthermore, the technical features in the embodiments corresponding to the technical features in each embodiment described in the summary of the invention can be replaced or combined as appropriate in order to solve some or all of the above-mentioned problems or to achieve some or all of the above-mentioned effects. Also, if a technical feature is not described as essential in this specification, it can be deleted as appropriate. [Explanation of Symbols]
